• Check the reliability of the MikroKopter.
• The flight battery and transmitter battery must be fully charged
• Watch for visible damage such as for loose screws, broken, unbalanced or damaged propellers, faulty connectors or solder joints, etc.
• The propeller must be in a good condition and securely mounted. The rotors must spin smoothly and there shall be no objects are in the rotational plane of the propellers and can get into it. Rotating propeller ends are dangerous to touch - never touch with fingers and other body parts a rotating propeller.
• Ensure the appropriate to the audible beeps when auto lipo-detection is enabled. 4 * beep means 4s Lipo
• Ensure that the channel of the remote control is free and you're within range of the transmitter
• The sensors must be calibrated (When the motors are off: move yaw- and gas stick into upper left corner until it beeps)
• Different settings can result in fundamentally different flight characteristics and occupation of the Channel functions. Make sure that you are familiar with the setting and its features
• After starting the motors, all motors must run and rotate evenly. Please fly carefully in small altitude until you know that everything is working fine.
• Perform a pre-flight check by (off checklist, see below)
• Start manually - switch off altitude control and GPS

Note: Get a good GPS lock if you are going the use the navigation functions. As soon as the green light on top of the GPS is blinking you have sufficient satellites to get GPS hold. The MK will automatically remember this as home when you calibrate the gyros, just be sure that the home position has some room around it because the MK might over run the home position a bit.
Warning: Come Home (CH) only works if you have GPS fix BEFORE the motor starts.
You should make sure you have GPS fix when your motor start otherwise it will return to the last 'home location' that it knows.
